IMPROVEMENT, m FABRIC ron CARPET-LINING, 8w."

The Schedule referred to in these Letters Patent and making part of thesame.

[T 0 all persons to/whmn thesepresen-ts shall come Belit known that we,J oHx L; KENDALL, of Foxborough, in the county of Norfolk and State ofMassachusetts, and RICHARD H. .TRESTED, of: the city, county, and Stateof New York, have invented a new and Improved Lining-for Carpets, 820.;and that the following is a full and complete specification of the lsame; reference being had tothe accompanying plate of drawings?- Q a Thepreseut invention relates to a new article of gma-nufacture, moreespecially designed for use as an under lining to carpets,galthough itmay be used for "otheripurposcs. a The invention consistsof-a'liningproduced from vegetable fiber, either alone .or in'combinationwitli aiiimal yfiber, by first reducing thesaid fiberto acon- .ditionoi',pnlp,"depositing the pulp in a sheetform, ow commonlypracticed in paper-making, 'and in \jecting such sheet-pulp, or fwater-leaf, after gbcen-dried in any suitable manner, to a mechan'icalaction of such a nature as will produce a;

"F breaking-up, as it were, of the fibrous sheet, giving it pliahility,elasticity, and softness, without destroy;

ing its homogeneity or continuity, ore-arising its disintegration,whereby the sheet is renderell suitable for a use as an-undcr lining forcarpets, 80c.

In carrying out this invention vegetable fiber, by preferencc'alonealthough animal fiber may becombined with it, of any kind] ordiuarilyused in paper-- making, is taken, and lthen' deposited-, 'in anysuitable manner, in a sheet form, as now practiced in paperrnaking.

, any suitable manner, it beingpreferable -to. place it in a chamber,which is s'uitablyheated"and"ventilated, when, having beentheroughly'died, it is then brought toa'i'pliable andelasticflconditionf by subjecting it To a mechanical action to ibreakup,-as it were,

the fibers of the sheet, destroying their hardness and compactness,without, however, afi'ecting the continnity or homogeneityiofythe sheet,whichv completes i "To reduce theJdrie-d .pulp-shectto a soft, pliable,and 3 elastic condition, as a'liovje' statedy 'one form of mechanismsuitable-therefor is shown in the accompany plate cf drawings,

The rollers B are similarly constructed, with'ribs, a, along theirlength,;at regular distances apart, as shownin the drawings, andparticularly at-D.

' ever, unbroken.

.pactness, and bringing'it to a pliable, soft, and elastic condition,with its continuity and homogeneity, how'- The action of the ribs a isto crease and flute the sheet, and thus to draw, loosen, or open, itsfibers frdinj each other, and, as a consequence, reducing the sheettothe condition above stated.

In lieu of the mechanism above described, other forms andarrangementsmay be employed, as, for in-v stance, the rollers, instead of beingribbed, may be consci-autumn teats or protuberances, or they may beconstructed; combining both ribs and teats. and, also, in lieu ofrollers suitably constructed 'to produce the effect desc ribed,;it maybeaccomplished bya directpoundingfnf'tliesheet with a device ordevices ofsuitable "construction, the mechanism, however arranged or constructed,forming no part of this invention',' i't-'relating simply to the articleof manuihcture, produced substantially-in the manner described.

The pulp-sheet may, if desired, have itsmoistnreremoved and its fibersset, as in paper-making, before being=dried, as hereinabove stated, andalso the dried pulp-sheet may "be calendered before being passed throughthe mechanism described, or its equivalent,

and the sheet sizedornohas in paper-making; but it is preferable not te'size or calender the fibrous sheet,

as, \rithontbeing-sizedor calender-ed, or both, it is susceptible ofbeing reduced to a more thoroughand r, perfect-suit and elasticcondition by anaction substant-ially as stated.

The lining herein described, it is obvious, may be produced in anylength, width, and thickness desired.

Having thus describedour invention, we will state our claim as. follows:

What we claim as our invention, and desire to have secured to us byLetters Patent, is-

As a new article of manufacture, a carpet-lining, made in the mannerherein described, and from vegetable fiber, either alone or combinedwith an animal The above s'pecificationof our improved lining forcarpets, &c., signcdby us this 18th day of February, A. D. 1870.
